asp.core同时兼容JWT身份验证和Cookies身份验证两种模式

在实际使用中，可能会遇到，aspi接口验证和view页面的登录验证情况。asp.core 同样支持两种兼容。 

首先在startup.cs 启用身份验证。

 var secrityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["SecurityKey"]));            services.AddSingleton(secrityKey);            services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)                .AddCookie(option =>    //cookies 方式                {                    option.LoginPath = "/Login";                 })            .AddJwtBearer(JwtBearerDefaults.AuthenticationScheme, options =>   //jwt 方式            {                options.TokenValidationParameters = new TokenValidationParameters                {                    ValidateIssuer = true,//是否验证Issuer                    ValidateAudience = true,//是否验证Audience                    ValidateLifetime = true,//是否验证失效时间                    ClockSkew = TimeSpan.FromSeconds(30),                    ValidateIssuerSigningKey = true,//是否验证SecurityKey                    ValidAudience = Configuration["JWTDomain"],//Audience                    ValidIssuer = Configuration["JWTDomain"],//Issuer                    IssuerSigningKey = secrityKey//拿到SecurityKey                };            });

Configure 方法中须加入

  app.UseAuthentication(); //授权  app.UseAuthorization(); //认证 认证方式有用户名密码认证            app.MapWhen(context =>            {                var excludeUrl = new string[] { "/api/login/getinfo", "/api/login/login", "/api/login/modifypwd" };  //注意小写                return context.Request.Path.HasValue                && context.Request.Path.Value.Contains("Login")                && context.Request.Headers.ContainsKey("Authorization")                && !(excludeUrl.Contains(context.Request.Path.Value.ToLower()));            }, _app =>            {                _app.Use(async (context, next) =>                {                    context.Response.StatusCode = 401;                });            });

 

在login页面，后台代码

            var uid = Request.Form["code"] + "";            var pwd = Request.Form["pwd"] + "";            var info = _mysql.users.Where(m => m.user_code == uid&&m.delflag==0).FirstOrDefault();            if (info == null)            {                return new JsonResult(new                {                    success = false,                    msg = "用户不存在"                });            }            if (info.pwd != pwd)            {                return new JsonResult(new                {                    success = false,                    msg = "用户密码不正确"                });            }            //创建一个身份认证            var claims = new List<Claim>() {                        new Claim(ClaimTypes.Sid,info.id), //用户ID                        new Claim(ClaimTypes.Name,info.user_code)  //用户名称                    };            var claimsIdentity = new ClaimsIdentity(                claims, CookieAuthenticationDefaults.AuthenticationScheme);            //var identity = new ClaimsIdentity(claims, "Login");            //var userPrincipal = new ClaimsPrincipal(identity);            //HttpContext.SignInAsync("MyCookieAuthenticationScheme", userPrincipal, new AuthenticationProperties            //{            //    ExpiresUtc = DateTime.UtcNow.AddMinutes(30),            //    IsPersistent = true            //}).Wait();            var authProperties = new AuthenticationProperties            {                //AllowRefresh = <bool>,                // Refreshing the authentication session should be allowed.                ExpiresUtc = DateTimeOffset.UtcNow.AddMinutes(60),                // The time at which the authentication ticket expires. A                 // value set here overrides the ExpireTimeSpan option of                 // CookieAuthenticationOptions set with AddCookie.                IsPersistent = true,                // Whether the authentication session is persisted across                 // multiple requests. When used with cookies, controls                // whether the cookie's lifetime is absolute (matching the                // lifetime of the authentication ticket) or session-based.                //IssuedUtc = <DateTimeOffset>,                // The time at which the authentication ticket was issued.                //RedirectUri = <string>                // The full path or absolute URI to be used as an http                 // redirect response value.            };            await HttpContext.SignInAsync(                CookieAuthenticationDefaults.AuthenticationScheme,                new ClaimsPrincipal(claimsIdentity),                authProperties);

　Controler控制器部分，登录代码：

[HttpPost("Login")]        public async Task<JsonResult> Login(getdata _getdata)        {            var userName = _getdata.username;            var passWord = _getdata.password;            var info = _mysql.users.Where(m => m.user_code == userName && m.delflag == 0).FirstOrDefault();            if (info == null)            {                return new JsonResult(new                {                    state = false,                    code = -1,                    data = "",                    msg = "用户名不存在!"                });            }            if (CommonOp.MD5Hash(info.pwd).ToLower() != passWord)            {                return new JsonResult(new                {                    state = false,                    code = -2,                    data = "",                    msg = "用户密码不正确!"                });            }            #region 身份认证处理            var secrityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_config["SecurityKey"]));            List<Claim> claims = new List<Claim>();            claims.Add(new Claim("user_code", info.user_code));            claims.Add(new Claim("id", info.id));            var creds = new SigningCredentials(secrityKey, SecurityAlgorithms.HmacSha256);            var token = new JwtSecurityToken(                issuer: _config["JWTDomain"],                audience: _config["JWTDomain"],                claims: claims,                expires: DateTime.Now.AddMinutes(120),                signingCredentials: creds);            return new JsonResult(new            {                state = true,                code = 0,                data = new JwtSecurityTokenHandler().WriteToken(token),                msg = "获取token成功"            });            #endregion        }

注意， 受身份验证的控制器部分，要加入如下属性头，才可以生效。 

    [Authorize(AuthenticationSchemes = "Bearer,Cookies")]    public class ControllerCommonBase : ControllerBase    {         }    

　

这样一个Controler 控制器，能够兼容两种模式啦。
